I have 8 pullets and they are 10 weeks old and I put them outside from being in our garage with their heating lamp 3 weeks ago and so 2 days ago I took the heating lamp out of their coop but have a tarp and blanket Over their coop, they seem to be fine since they are fully feathered, but tonight I walked outside and it was a little warm out but it was lightly raining and they where huddled On the hay stack in the rain instead of in their coop, is that normal??? I guess in just being paranoid of loosing them but will they be okay during the winter without the heating lamp? Did I make the right decision of removing it? I make sure their coop is fully protected from the wind and rain, plus they are fully feathered, just need peace of mind! Thank you!
